Tony,
I probably did not make myself clear. No surprise there! When I am forced to change the filename for any reason, I lose track of the original camera generated file name. I use the camera generated name as a sort of image serial number. It takes time to enter it manually in the key words and sometimes I forget

. Here is an example of when it would be handy. When I post images to Flickr, I may have several very similar images. When someone asks for a reprint it can sometimes take me a while to file the exact digital Negative. If it was already in the keywords I could find it quick. Having the original camera generated filename makes it easy for me.
Thanks for your reply
Mike
